Abstract

Sweet corn is a horticultural commodity that is widely cultivated in Indonesia. This study aimed to determine the development and growth response of sweet corn plants to the application of different doses of micro inorganic fertilizer (3.14% Zn – 2.54% Cu). The research was conducted at Sindangbarang Experimental Field, Bogor, West Java. This experiment used a Randomized Complete Block Design (RCBD) with a single factor, namely the dose of fertilizer application. Treatments were arranged in 4 levels of application, namely: (1) control, (2) standard NPK, (3) NPK + 1 micro dose, (4) ¾ NPK + 1 micro dose. The results of this test indicate that the application level of micro inorganic fertilizers at the application level of NPK fertilizer + 1 micro dose and ¾ NPK + 1 micro dose fertilizer treatment can generally provide plant height, stem diameter, number of leaves, cob length, cob diameter, stover weight, cob weight with husk, cob weight without husk, production per plot, and productivity which were statistically higher than the control treatment. The application of NPK + 1 micro dose and fertilizer treatment of ¾ NPK + 1 micro dose have Relative Agronomic Effectiveness (RAE) values that meet the requirements to pass the fertilizer effectiveness test, with the highest RAE value obtained in the application of ¾ NPK + 1 micro dose fertilizer at 118%.

Abstract

Sweet corn (Zea mays L. var saccharata) is a valuable crop whose productivity depends not only on macronutrients but also on micronutrients such as zinc (Zn) and boron (B), which play essential roles in plant physiological processes. However, the effectiveness of foliar-applied micronutrients in sweet corn cultivation under tropical conditions remains insufficiently studied. This research aimed to evaluate the agronomic effectiveness of a micronutrient fertilizer containing Zn (5.46%) and B (3.59%) when combined with reference and reduced doses of NPK fertilizer. The experiment was conducted from February to May 2025 at the Sindangbarang Experimental Farm, IPB University. This experiment was conducted using a randomized complete block design with four treatments, namely control (no fertilizer), reference fertilizer, reference fertilizer + 1 dose of micronutrient fertilizer, and ¾ dose of reference fertilizer + 1 dose of micronutrient fertilizer, with six replications. Results showed that micronutrient application significantly enhanced vegetative growth and yield components compared to the control. The combination of reference NPK and one dose of micronutrient fertilizer produced the highest productivity, with a 78.8% increase over the control and a relative agronomic effectiveness (RAE) value of 114.5%, indicating a 1.14-fold improvement over the reference treatment. These findings suggest that integrating Zn and B into fertilization strategies can enhance sweet corn performance and support more efficient nutrient management in tropical agroecosystems.
